Lord Sainsbury of Turville: Oil is a globally traded commodity and therefore the UK's recent crude oil trade deficit does not reflect a potential disruption to domestic supplies. As part of the Government's Climate Change Programme, various policies are in place to promote energy efficiency across the economy, including the road transport sector where most oil is consumed. These include EU-level voluntary agreements with car manufacturers on the fuel efficiency of new cars and company car tax rules. In addition, the Government recently announced the creation of the Renewable Transport Fuels Obligation (RTFO) to introduce renewable fuels into the transport system. The RTFO announcement said that, by 2010, oil companies would be obliged to ensure that 5 per cent. of the fuel they sell is made from renewable biosources.
